Multicystic dysplastic kidney in children (MCDK)

Multicystic dysplastic kidney (mul·​ti·​cys·​tic - dys·​pla·​sia - kid·​ney) or MCDK occurs when one of the kidneys does not develop properly while in the womb, and has many cysts (fluid-filled sacs) and scar tissue.

What is a multicystic dysplastic kidney in children (MCDK)?

Multicystic dysplastic kidney is a common disorder in which one kidney doesn’t properly form during fetal development.

The kidneys begin to develop in the first trimester of pregnancy and, if something goes wrong, the fetus can end up with one non-functioning kidney that is full of cysts and scar tissue.

In most cases, the other healthy kidney can successfully take over the functions of the non-functioning kidney, such as removing waste from the blood and creating urine.
